The Dorman 911-240 Turbocharger Diverter Valve is a direct-fit replacement that restores proper boost control by matching the fit and function of the original valve.

If your vehicle is experiencing boost leaks, flutter, or reduced turbo response due to a failed diverter valve, this Dorman unit offers an engineered replacement designed for durability and dependable performance.

How does this diverter valve restore turbo performance?

Replacing a worn or cracked diverter valve stops unmetered air escape and returns the turbocharger system to correct pressure management. That helps the turbo spool predictably and reduces symptoms like hesitations or loud bypass noises.

• Matches original valve fit and port locations for straightforward installation.
• Replaces a failed diaphragm or leaking seal that allows boost loss.
• Restores proper pressure bleedoff to the intake or atmosphere as originally designed.

Will this part fit my vehicle and how do I confirm fitment?

Dorman provides a vehicle compatibility check to ensure this specific 911-240 valve fits your make, model, and trim. Always verify fit using the seller’s garage or fitment tool before purchase to avoid returns or incorrect parts.

• Enter your vehicle details in the garage tool to confirm exact fitment.
• Look for additional notes in the product fitment area (such as Amazon Confirmed Fit) before ordering.

What materials and quality measures are used in this replacement valve?

This diverter valve is made from robust materials selected to withstand under-hood temperatures and mechanical cycling typical of turbo systems. Dorman’s manufacturing and testing standards aim to deliver a predictable service life comparable to the original equipment part.

How difficult is installation and what should I prepare for?

Installation complexity is similar to the original part’s replacement and typically requires basic hand tools and a safe workspace. Depending on vehicle layout, you may need to remove intake components or engine covers to access the valve.

• Prepare basic tools: screwdrivers, pliers, and possibly a socket set.
• Inspect hoses and connectors while installing and replace any brittle or damaged lines.
• Follow torque recommendations and check for leaks after installation.
